235 is the example result. Read it using the units and relationship stated below.
Solar Appliance Load uses device 1 (w), device 2 (w), device 3 (w).
Distinguishing electrical arithmetic from equipment selection
For solar appliance load, the relationship is Result = [Device 1 (W)] + [Device 2 (W)] + [Device 3 (W)]. The amount depends on the supplied device 1 (w), device 2 (w), rather than a live market price or a value imported from another record. Power, energy, voltage and current describe different quantities. Watts represent a rate; watt-hours represent energy over time. Battery and inverter losses can reduce usable runtime even when the rated capacity is unchanged.
What the model includes
Result = [Device 1 (W)] + [Device 2 (W)] + [Device 3 (W)] Read unit labels before comparing results. Motor estimates depend on phase, efficiency and power factor; energy budgets depend on duration and duty cycle. Nameplate values and measured consumption may differ under real loads. Treat the output as the stated estimate. It does not select a code-compliant conductor, protective device or complete installation. Equipment specifications and applicable requirements remain part of the design decision.
Example with the supplied inputs
Device 1 (W): 100; Device 2 (W): 75; Device 3 (W): 60. Result: 235. The values are illustrative.
Compare one changed input
Device 1 (W) changes from 100 to 110. The result becomes 245. All other inputs remain fixed.
Calculation rule
Result = [Device 1 (W)] + [Device 2 (W)] + [Device 3 (W)]
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Device 1 (W) | 100 | Use the source quantity represented by device 1 (w). Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Device 2 (W) | 75 | Use the source quantity represented by device 2 (w). Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Device 3 (W) | 60 | Use the source quantity represented by device 3 (w). Keep the counted population fixed and avoid mixing a unit value with a period total. |
Output: 235 is the example result. Read it using the units and relationship stated below. Use the formula to distinguish a cash amount, count, percentage or ratio.
How to use the page
Collect the inputs
Gather Device 1 (W), Device 2 (W), Device 3 (W). Use one period and the units shown in the form.
Run the calculation
Enter the values and select the action. The calculation rule above explains how the inputs produce the result.
Compare a scenario
Change Device 1 (W) on its own, keeping the other inputs fixed. Read both results before changing another assumption.
Worked example
With the example inputs listed above, the result is 235.
Change Device 1 (W) from 100 to 110 while keeping every other value fixed. The result becomes 245. This comparison isolates that input; it does not forecast how other variables will respond.
Check the stated formula, units and limits before using the result in a decision.
